I can start the game, but I don't know if it will effect the game later or not. Any fixes to this?

Thanks~

EDIT: I checked all the settings, and the files directory are all seem to be in the right place. I uninstalled and installed it again but yeah, same thing happens.Sorry if this question has been answered before I couldn't find the solution here

You're running the game on Intel HD Graphics and it doesn't support the postprocessing effect that comes with the shader. You either need to assign the game to a dedicated GPU (if you have one) or go into Workshop -> OpenGL -> Graphics and uncheck the box for Postprocessing.
